Dream team session
Good drainage and nutrient/moisture retention Tolerant to compaction Sandy loam, clay loam Is organic matter content important? ◦ Very important for root development and nutrient/moisture retention
Distribution critical ◦ Pollination: < 0.2 PET ◦ Nut Size: 0.2 – 0.4 PET ◦ Oil Accumulation: 0.5 – 0.6 PET Would you utilise irrigation? ◦ Need depends on rainfall pattern ◦ Irrigation critical for Nut Size and Oil Accumulation period when rainfall inadequate
Sufficient to provide economies of scale for cost efficient operations Would it be staged plantings or all in one planting? ◦ Plant schedule dependent on finance and availability of preferred grafted cultivars for the site
HAES: 294-Purvis, 344-Ka’u, 508-Kakea, 800-Makai Would you use pollinators? ◦ Cultivars to serve as pollinators for each other.
Minimum: 7.6 x 7.6 meters or greater What row configuration would you plant? (east/west or north/south or on the contour?) ◦ North-South What is the maximum length per row? ◦ 500-600 meters
Would you mound the rows? ◦ Not Necessary ◦ Grade land to allow mechanized operations(planting shade tolerant grasses?) ◦ Establish grassed water-way on a contour at 150 to 300 meter interval within the field to trap eroded soil and minimize run-off into streams.
Year 5 production target = 0.03 (tonnes of SK/ha) Year 10 production target = 0.68 (tonnes of SK/ha) Year 20 production target = 1.41 (tonnes of SK/ha)
Please incorporate any additional ideas/points/issues you feel are important. ◦ Compile as much environmental data for orchard site: Climate, Soil, Irrigation ◦ Select Cultivars with compatible bloom periods, nutrient requirement, drought tolerance, pest resistance, kernel quality retention during delayed harvest. ◦ Cultivar growth rate at selected site to determine tree space and plant configuration
